I included all of the player's seasons assuming they actually had an inning pitched, and when they appeared for several teams, I also included both league and season totals (if those are different). For those the team is TOT. This means that you can not read down the line to get the season totals.

Here is a run down of the columns.

Year - Year in which the season occurred

Ag - Age the player was on June 30th of that year.

Tm - Team they played for (see Team ID's)

Lg - League they played in (AL- American League, NL- National League)

W - Wins

L - Losses

G - Games pitched in

GS - Games started

GF - Games finished in relief (does not include complete games)

CG - Complete Games

SHO - Shutouts

SV - Saves

IP - Innings Pitched

H - Hits

R - Runs Allowed

ER - Earned Runs Allowed

HR - Home Runs

BB - Base on Balls or Walks

SO - Strikeouts or whiffs or K's

HBP - Hit Batsmen

WP - Wild Pitches

BFP - Batters Faced Pitching, for some ancient years this may be an estimate

ERA - Earned Run Average 9*ER/IP

lgERA - Earned Run Average for a league average pitcher in that ballpark or combination of ballparks.

ERA+ - the ratio of the league's ERA (adjusted to the pitcher's ballpark) to that of the pitcher. > 100 is above average and < 100 is below average. lgERA / ERA

WHIP - Walks + Hits Allowed / Innings Pitched

End Notations (CYA, MVP, ROY) - Tacked onto the end of the pitching lines are notations if the player was an All-star (AS), or received votes for the MVP, Cy Young Award (CYA) or Rookie of the Year (ROY). Their rank in those awards is also listed.

GDP or GIDP - Grounded into Double Plays (induced by the pitcher)

hmR/G and rdR/G - average runs per game allowed by this team in home and road games.

Below that is their career record (along with their career won-loss percentage).

Career "High"

The career high in each category is listed next. Note that high is meant here as most extreme. Obviously, you are more interested in their lowest ERA and not their highest. It also is not their best season, but the best from all the categories. You can quickly see what Nolan Ryan's career highs in strikeouts were along with his most Innings Pitched in a season. I required 40 innings pitched in a season for an ERA to qualify as career best.

Team Pages

The pitchers are listed as follows. First any starters with more than ten games started and most of their appearances as starters are listed. Next, we list the leader in saves (when more than 9) and then the relievers appearing in the most games. Next, we list other starters and then other relievers. It isn't a perfect setup and I'm open to other suggestions.
